HAT-SEWING MACHINE.

Specification of Letters Patent.

Patented Nov. 5, 1918.

Application filed November 22, 1916. Serial No. 132,756;

To all whom it may concern:

Be it known that I, ALFRED Gums, a citizen of the United States, residing at Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Hat-Sewing Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to sewing machines adapted for sewing sweat bands into hats, and it has for its object to provide convenient and effective means adapted to support a hat during the stitching operation and so constructed and arranged as to permit the easy introduction of the hat into stitching position and its easy removal therefrom after the completion of a stitching operation.

The improvement may be applied to the machine forming the subject of my Patent No. 1,206,133, issued November 28, 1916. In

the machine disclosed in said patent, the hatsupporting disk is mounted between the .presserand feed-members but adapted to slightly adjust itself to inequalities in the material. In order to introduce a hat into stitching position in said machine, the hatsupporting disk and presser-member are moved away from the feed-member. To

facilitate this operation I have now mounted the hat-supporting disk so that it can be swung away from operative position in a plane intermediate the presserand feedmembers, leaving a clear space for the introshoulder on the disk-supporting lever and forcibly move the hat-supporting disk away from operative position to provide a clear space for the removalof the hat. The initial actuation of the latch may be supplemented by gravity in moving the hat-supporting disk to extreme retracted position. When the hat-supporting disk is in retracted position its carrier rests upon a stop provided for the purpose.

In the accompanying drawings, Figure 1 is a front elevation of the machine showing the hat-supporting disk in both operative and inoperative positions, the latter position being indicated by dotted lines; Fig. 2 is a plan of" the presser-arm partly in section, illustrating the mounting of the hat-support thereon and the mechanism for moving the hat-support into and out of operative position; Fig. 3 is a side elevation of the'complete machine and Fig. 4 is a perspective View showing the supporting bracket and disk-supporting lever.

As illustrated in the drawings, the base 1,

bed-plate 2, casing 3, balance wheels 4, looper 5 feed-member or wheel 6, presser-member or wheel 7 and presser-arm 8 or support for the presser-member, are all substantially like the parts of the machine described in my patent above referred to.

Secured to the pressenarm' 8 by means of a set-screw 9 is a pin 10 upon which is fulcrumed a horizontally disposed bracket 1.1 having a lateral arm entered by a screw stud 12 upon which is pivotally mounted an upwardly extending plural-armed lever or carrier 13 having near its upper end a spherical-headed or ball-stud 14 embraced by cap-pieces 15 secured by screws or otherwise to the hat-supporting disk 16 having its periphery in a plane intermediate the feed and presser-members or wheels; Embracing the pin 10 is a coiled spring 17 with one end' entering a suitable aperture in the presserarm 8 and its other end entering an aperture in the hat-disk sustaining bracket or support 11, the spring retaining the bracket 11 with its hat-supporting disk 16 in retracted or lower position with respect to the pressermember 7 and feed-member 6. In order to adjust the hat-supporting disk 16 with respect to the presserand feed-members, a thumbscrew 18 is provided, which enters a threaded aperture in a lug 19 formed on the presser-arm 8, the end of the thumb-screw 18 bearing against 'a suitable lug of the bracket 11.. By turning the thumb-screw, the bracket 11 is adjusted about its pin 10 against'the stress of the spring 17. i

Secured to the laterally projecting arm 20 of the lever 13, by suitable fastening screws 21, is the segmental guide-plate 22 extending to a point adjacent to the hat-supporting disk 16 at the stitching point.

In order to retain the hat-supporting disk 16 and segmental guide-plate 22 in operative position between the adjacent presserand feed-members, the lever 13 is provided with a lateral. arm 23 whose upper face is formed with a shoulder 21 adapted to be engaged by the latch 25 adjustably secured by the tastening screw 26 upon the operating handlelever 27 journaled upon the screw-stud 2S entering the bracket or support 11. The latch is spring-pressed againstthe lug of the lever 13 by means of the coiled spring 29 embracing the screw-stud 28 with one end 30 entering a suitable aperture in the leverhandle 27 and its other end resting against a lug 31 on the bracket 11. Formed integral with said handle is a projecting pusher-finger adapted to engage the under face of the shoulder of the lever 13 and thereby force the lever, with its hat-supporting disk 16 and segmental hat-guide 22, out of operative position as shown in dotted lines in Fig. 1, to provide a clear s )ace between the feedand presser-inen bers for the introduction of a hat. Entering the lug 31 is a screw forming an adjustable stop for the lever 13 when in operative position, the screw 33 be-- ing locked in any desired position of adj ustment by the am-nut 31. hen the hat-supporting disk 16 and segmental hat-guide 22 are out of operative position, the arm 20 oi? thelever 13 rests upon asupport comprising a leather buffer 35 secured by a fastening screw 36 to a lateral spring-arm 37 carried by, and.

fastened by screws 38 to, the presser-arm S.

Secured to the presser-arm 8, near the bedplate 2, by the screw 39 is a dow iwardly extending arm 40 forming a support for the pivot-pin ail clamped therein by the fastening screw 12. Journaled upon the pin is a rocker in the form of a bell-crank 13 whose upwardly extending arm 11 is entered by a screw-stud 45 embraced by one end of a bent link 16 whose other end has a pivotal connection, by means of the screw-stud 47, with the lateral arm 23 of the lever 13. The other arm #58 of the rocker 13 is suitably apertured to receive a link or chain +9 adapted to be operatively connected with a kneeor treadle-plate (not shown).

vVhen it is desired to begin a stitching operation the lever-handle 27 is depressed to release the latch 25 from contact with the shoulder 2a of the lever 13 carrying the hatsupporting disk 16 and segmental hat-guide 22, the pusher-finger 32 of the operating handle-lever forcibly shifting the lever 13, with the parts carried thereby, out of opera tive position and into retracted position, as shown by dotted lines in Fig. 1, so as to provide a clear space between the presserand feed-members. These members are normally maintained in yielding contact but may be separated for introduction of the work by devices shown and described in my patent application above referred to.

lVhen the work has been introduced between the presserand feed-members, the hat-supporting disk and segmental hat-guide are swung upwardly into operative position by actuating the kneeor foot-plate conneeted with the rocker 43. As the disk is moved into operative position by actuating a kneeor foot-plate, the operators hands are left free to handle the work and properly adjust it for the stitching operation.

The operating handle-lever with its latch and pusher-finger constitutes a common element for retaining the disk 16 with hatguide 22 in operative position and for positively insuring their movement out of stitching position when it is desired to introduce or remove the work.

Having thus set forth the nature of the invention, what I claim herein is 1. In a hat sewing machine, the combination with stitch-forming mechanism, of opposed ieedand presser-memhers, a hat-supporting disk having its periphery in a plane intermediate said feed and presser-mem,bers, and means for moving said hat-supporting disk into and out of operative relation with said stitch-forming mechanism.
